T/GDEIA 5-2018 Reverse osmosis membrane functional coating machine

Scope

Scope: This standard specifies the terms and definitions, models and types, basic parameters, equipment composition, technical requirements, test methods, inspection rules, marking, packaging, transportation, and storage for the production of reverse osmosis membrane coating machines; This standard applies to reverse osmosis membrane coating machines used for two-step coating processing on substrates such as nonwoven fabrics; Main technical content: The coating machine is mainly composed of unwinding devices, material storage devices, coating devices, drying and cooling devices, winding devices, and control systems. Reverse osmosis membrane coating machines use one-step or two-step methods to evenly coat the coating material on the substrate surface and meet the specified reverse osmosis membrane process requirements. Substrate width (mm) ≤ 1650; Coating width (mm) ≤ 1600; Roll surface width (mm) ≤ 1750; Machine speed (m/min) ≥ 15; Oven temperature accuracy (℃) ≤ ±1; Maximum tension (N/m) 200; Tension accuracy (%) ≤ ±2; Winding end face accuracy (mm) ≤ ±2. The specific coating method and the selection of the number of coating heads depend on the formulation parameters of the coating solution, temperature, and the requirements of the coating structure.
